THE RIDDLE

A window to my soul and a door to my thoughts.

A prism to the world that grows so dark and bright.

Poets of ages imagined this beauty behind a veil of illuminations.

but found a seducer of nations and a manipulator without a spoken word.

Circular in motion, white at the fringes. The core is colored by destiny.

Guarded by shadow soldiers strong as steal and light as feathers.

In a panic they flicker to protect this diamond of creation.

WHAT AM I?
